Ive spent much time assisting collectors and museums evaluate/identify/authenticate artifacts over the decades... I immediately saw lots of issues with that image. When its looked at in more detail from a forensic standpoint... Its way way off... and that generally further confirms it is not Jeff Davis.
Not sure if the guy that bought it for 23K got it for an investment for later resale... but may quickly get a rude awakening once a historical professional examines it... Hope he/she is single.. if they arent...they probably soon will be...lol..
